Check out these emulated calculators at the Internet Archive

The Internet Archive calls this new collection the Calculator Drawer. There are 14 calculators to choose from, including the HP 48GX, TI-82, TI-83 Plus, and even the Electronic Number Muncher, which is an 80s-era toy calculator. The Internet Archive doesn’t just emulate the interface of each device, either; it incorporates their physical design and buttons, making it feel like you have the actual device right in front of you.
